Emu XL-7 & MP-7 User's Group

Hi,
i'd like to know haw can i export midi from Sonar
to upload it to my XL7 and if i can then re-assign the
bank/preset to every single midi channel.

I've tried to export one song to MIDI and then upload it
to XL7 but i can't do nothing with the presets-channel.
Please Help me,
Bye
Erik
